Canadian beaver

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.

Sphacelaria tribuloides is a small, tufted brown alga forming compact cushion-like colonies on rocky substrates and larger algae. It inhabits intertidal and shallow subtidal rocky zones in temperate and tropical seas worldwide. This photosynthetic alga reproduces via characteristic star-shaped propagules and colonizes rocky marine surfaces.
